Description

Technical Field

[0001] The utility model relates to the technical field of compressors, in particular to a rotor compressor with a detachable hook. Background Art

[0002] Rotary compressors are widely used in refrigeration equipment such as air conditioners. Rotary compressor manufacturers need to hoist the compressors on a conveyor line during the assembly process in the factory; and the top cover of the shell also needs to be transported on the conveyor line before being welded to the lower shell. However, the top cover has no place to be hung, which makes transportation inconvenient and inconvenient for automated production, thus reducing production efficiency. Summary of the invention

[0003] The purpose of the utility model is to solve the problems existing in the above-mentioned prior art and to provide a rotor compressor with a detachable hook.

[0004] The specific scheme of the utility model is: a rotor compressor with a detachable hook, including a shell, a motor and a mechanical part are installed in the shell, a terminal and a connecting screw are installed on the top cover of the shell, an external thread is provided at the outer end of the connecting screw, the connecting screw is used to fix the terminal box, the top end of the connecting screw is threadedly connected with a hook, the upper part of the hook is provided with a bent hook part, the lower end of the hook is provided with a connecting part, and the connecting part is threadedly connected to the connecting screw.

[0005] Furthermore, the diameter of the connecting portion is larger than that of the connecting screw and a blind hole is provided at the bottom end, and an inner wall of the blind hole is provided with an internal thread matching the connecting screw.

[0006] Furthermore, the connection portion has a smaller diameter than the connection screw and is provided with an external thread, the end of the connection screw is provided with a blind hole, and the inner wall of the blind hole is provided with an internal thread matching the connection portion.

[0007] Furthermore, the hook portion and the connecting portion are integrally formed.

[0008] Compared with the prior art, the utility model has the following advantages: the original connecting screw rod has diversified functions and can not only be used to fix the terminal box, but also can be connected with the hook for hoisting during the production and assembly of the compressor, thereby facilitating transportation on the conveyor line.

[0012] Embodiment 1

[0013] See also Figure 1 The present embodiment is a rotor compressor with a detachable hook 3, comprising a shell 1, in which a motor and a mechanical part are installed, a terminal and a connecting screw 2 are installed on the top cover of the shell 1, an external thread is provided at the outer end of the connecting screw 2, the connecting screw 2 is used to fix the terminal box, a hook 3 is threadedly connected to the top end of the connecting screw 2, a bent hook portion 32 is provided at the upper part of the hook 3, a connecting portion 31 is provided at the lower end of the hook 3, the connecting portion 31 has a smaller diameter than the connecting screw 2 and is provided with an external thread, a blind hole is provided at the end of the connecting screw 2, and an internal thread matching the connecting portion 31 is provided on the inner wall of the blind hole.

[0014] Furthermore, the hook portion 32 and the connecting portion 31 are formed in one piece, thereby improving the strength of the hook 3 .

[0015] Example 2 See Figure 2 The structure of this embodiment is basically the same as that of the first embodiment, except that the diameter of the connecting portion 31 is larger than the connecting screw 2 and a blind hole is provided at the bottom end, and the inner wall of the blind hole is provided with an internal thread matching the connecting screw 2.

[0016] During the assembly production process in the factory, the hook 3 is threadedly connected to the connecting screw 2 so that the compressor is provided with the hook 3, and the compressor is transported on the conveyor line by hoisting the hook 3.
